Interface PointerState

A normalized pointer event (mouse, pen, touch — same shape).

Coordinates are target-relative when a HTMLElement target is passed (using getBoundingClientRect()); otherwise they're page coordinates.

interface PointerState {
    x: number;
    y: number;
    dx: number;
    dy: number;
    isDown: boolean;
    event: PointerEvent;
}

Distance since the previous event on the X axis.
